 xlvi., fig. 10. 



Length of tho male 1£ line. 



Cephalo-thorax, logs, palpi, and falcos yellow, slightly tinged 

 with orange ; the tibico of the two first pairs of logs a little 

 dusky. 



Abdomen dull yellow-brown. The height of the clypeus 

 exceeds half that of the facial space. 



Legs short and tolerably strong, 4.1.2.3. Spines very few and 

 slender ; on the two first pairs thoy are simply strong bristles. 



Palpi short ; the cubital joint has a single, slender, not very 

 long, straight, tapering black bristle directed forwards from near its 

 fore extremity on the upper side ; the radial joint is stronger than 

 the cubital, a little obtusely produced in front, and slightlygibbous 

 behind. Digital joint large, slightly prominent towards the base 

 near the outer side, at about the middle of which there is a 

 slight lobe ; palpal organs prominent and complex ; on the 

 outer side, at their base, is a large, somewhat concave, crescent- 

 shaped process, at the upper margin of which are two small 

 prominences, the postorior prominence being the stronger. 



Found on the Cheviot Hills.

 not long attained maturity, the colours had not deepened to their 

 propor hue, and were not therefore reliable. Legs longish and 

 slender; spines few and fine. Palpi short; digital joint of 

 moderate size, with a small, somewhat conical prominence near 

 its base on the outer sido. Palpal organs moderately complex,
